buickanddeere said: (quoted from post at 08:53:45 01/12/14) The 302 Z28 engine was 290 flywheel HP. It was the optional dual four barrel cross ram intake, high performance cam, valve springs and open tubular headers that made the 302 into an 8000 rpm engine.
1969 Z28, NHRA F/Stock, 302, all factory except headers as per the rules, SINGLE four barrel, 5.56 rear end gear, 9000 RPM launches and shifts, eight inch Racemasters, 11.80 in the quarter mile. This was in 1972. The dual four cross ram turned it into a 11000 RPM engine. The other changes you mentioned along with some head porting turned it into a Super Stocker, running in the 10's. Today, the same car turns the quarter in the low 9's, launches at 14000 RPM, but has a lot more changes, like tube chassis for starters, big tires, cage, and so on. Wish I still had it, but it would take near $200K to get it back now.

Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
